Instructables user whamodyne made a self-watering planter from a rag and a 2-liter plastic bottle:

I have a black thumb due to my forgetfulness on the watering of plants. By the time I remember and rush over with the wattle bottle, the plants have croaked and moved onto the next plane of existence.

I was reading some furniture blogs (doesn’t everyone?) and noticed this post. It’s a great idea and something like the earthboxes my mom grows tomatoes in, but the cost?!!? $55? That seems a bit much.

I decided to make something like that using a 2 liter bottle and a rag from an old t-shirt. Much lower cost and a nice weekend project.
